SU(3) implications of the observation of the A$_{1}$ and C mesons
A new determination of the Q/sub A/-Q/sub B/ mixing angle and of the antisymmetric coupling for the vector-pseudoscalar decay of the axial vector mesons is presented. This uses information from the decay rates of the A/sub 1/ and C mesons found in the study of baryon exchange processes in K/sup -/p...

Sumario: | A new determination of the Q/sub A/-Q/sub B/ mixing angle and of the antisymmetric coupling for the vector-pseudoscalar decay of the axial vector mesons is presented. This uses information from the decay rates of the A/sub 1/ and C mesons found in the study of baryon exchange processes in K/sup -/p interactions at 4.2 GeV/c combined with the decay rate B to omega pi . The consistency between the results obtained from backward produced A/sub 1/ and C and diffractively produced Q/sub 1/ and Q/sub 2/ is discussed. (22 refs). |
